Storage is getting cheaper but the growth curve doesn't have the right exponent because we don't have the battery science or the battery technology to meet grid scale energy needs. You need energy storage at scale at night. The only solution at night after batteries (chemical, stored water, gravity, etc.) are quickly depleted is natural gas. Modern nuclear reactor designs could easily fill the gap. Public sentiment and the risk of building in earthquake prone geography has prevented investment in nuclear.
